Is it normal when your boyfriend didn't call you within 5 days after an argument?

we're both 21 and in a long distance relationship for four years. so we had an argument about him being insensitive and disrespectful, so I told him I don't want him to treat me like that. but while I was talking he ended up the call thus making me more pissed at him. so I told myself that I won't call him unless he calls me first and ask for an apology, but he never did. what should I do?
